When calling the .toBuffer() method on a sharp object, I get the following error:
Input buffer contains unsupported image format
I'm fetching an image from S3, and I am certain its retrieved as a Buffer which is then passed to sharp.
Moreover, when I console.log the base64 of the buffer and check what's behind, I do get the original image and the filetype is jpeg, so I can't seem to figure out why it would say that the Input buffer contains unsupported image format.
const imageBuffer = fileFromS3.Body
console.log(imageBuffer)
console.log(imageBuffer.toString('base64'))
let result = await sharp(imageBuffer)
.toColourspace('b-w')
.sharpen()
.toBuffer()
When I check the sharp object before running toBuffer() I get this data in the object:
let result = await sharp(imageBuffer)
.toColourspace('b-w')
.sharpen()
console.log(result)
Prints:
